LighTech Front & Rear Axle Nut Aprilia RSV4 / RSV4 1100 Factory / R / RR / RF (2009–2026) D001

When every gram counts on track, the LighTech axle nut D001 delivers where it matters most. Machined from aerospace-grade Ergal 7075 aluminium and anodised for lasting durability, this front and rear axle nut is engineered specifically for the Aprilia RSV4 platform — giving serious RSV4 racers and trackday riders a genuine performance upgrade over the stock steel item without compromising a single newton-metre of clamping integrity.

Key Features

• Aerospace-grade Ergal 7075 aluminium construction — exceptional strength-to-weight ratio trusted in aviation and motorsport alike
• Precision CNC-machined for an exact, rattle-free fit on both front and rear axle positions of the RSV4 and RSV4 1100
• Hard anodised surface finish resists corrosion, track chemicals and heat cycling while maintaining a clean racing aesthetic
• Rated to a maximum torque of 140 Nm — fully compatible with manufacturer axle torque specifications
• Available in five anodised colours to coordinate with your RSV4's livery or team colours
• Direct OEM replacement geometry: M25x1.5 thread, 39 mm diameter, 13 mm height, 30 mm hex diameter

Track-Proven Engineering

LighTech designed the D001 with the demands of circuit racing firmly in mind. The Ergal 7075 alloy used throughout is the same material specified by aerospace engineers for structural components where mass reduction cannot come at the cost of tensile strength. CNC machining to tight tolerances ensures the nut seats perfectly against the fork leg or swingarm — eliminating the micro-movement that can develop with lower-grade aftermarket hardware over repeated track sessions. The hard anodised finish is not merely cosmetic; it forms a protective oxide layer that resists the abrasive grime, chain lubricant overspray and brake dust that accumulate during hard use at the circuit. Whether you are stripping kilos for a sprint race or simply elevating your RSV4's detail quality for trackdays, the D001 provides a measurable and visible upgrade.

Road Use & Everyday Reliability

The D001 is equally at home on the road. The maximum rated torque of 140 Nm means it meets the clamping demands of road riding without reservation, and the corrosion-resistant anodised finish ensures it stays presentable through all-weather commuting and touring. Fitting is straightforward using a standard 30 mm hex socket — no specialist tooling required. The nut is supplied in black (D001NER), gold (D001ORO), red (D001ROS), silver (D001SIL) and cobalt blue (D001COB) so you can match or contrast your RSV4's colour scheme precisely.
